I have a Dell Inspiron 5000 series. I don’t have the computer with me this is for a user and purchased a computer for. I think it says Dell Inspiron 15 on the front. Anyway, this employee wanted a spare power adapter so I bought them one directly from Dell. It looks a tiny bit different but it is a Dell power adapter and it has the same power specs on the back. He plugged in this new power adapter and turned on the computer and noticed that it would charge for about two minutes and then say not charging. So he turned off the computer plugged in the original power adapter and now that power adapter will not charge this computer. I have no idea what to tell him or what the issue is. Any ideas?
